推荐答案

奇拉格已经正确地指出了解决方案。 我只想补充一点，活动的启动无关的AsyncTask的在里面。默认情况下，当有任何配置的变化，该活动将重新启动，除非在配置变化由活动显式处理。这是通过在manifest文件中的条目进行。

Chirag have already correctly pointed out the solution. I just want to add that, restart of Activity has nothing to do with the AsyncTask in it. By default, when there are any config changes,the activity is restarted UNLESS the config change is explicitly handled by the Activity. This is done by making an entry in manifest file.

注意：检查code的设备没有在模拟器。因为我曾遇到类似的问题更早。同样的code没有工作的仿真器，但它的工作对设备完美。因此，增加对安卓入门：configChanges 在清单和检查Android设备，而不是仿真器上的应用程序

NOTE: Check the code on a device not on emulator. Because I had faced similar problem earlier. The same code didn't worked on emulator but it worked on device perfectly. So add the entry for android:configChanges in manifest and check the application on a android device instead of emulator.

和我第二@hackbod。 不要只在必要！

And I second @hackbod. Do it only if necessary!
